. Electrical Safety-Related Work Practices Only qualified workers who have been trained in the avoidance of electrical hazards are permitted to work on or near exposed energized parts. An arc flash (also called a flashover), which is distinctly different from the arc blast, is part of an arc fault, a type of electrical explosion or discharge that results from a low-impedance connection through air to ground or another voltage phase in an electrical system. Terms of Use - When using electricity in a wet or damp location, including outdoor locations, a Ground Fault Circuit Interrupter (GFCI) must be used. All injuries and near-misses, including those potentially caused by electricity or electrical equipment, must be reported using the Online Accident Reporting System (OARS). Some electrical devices pose a higher threat to life because of high voltage and high electrical power, so workers must take further safety precautions when dealing with these devices. B    These records should be made available for review and inspection. . . We rely on electricity, but sometimes underestimate its capability of causing injury. Electrical safety refers to any safety precautions taken against electricity. (wiki), A ground fault circuit interrupter (GFCI), also called Ground Fault Interrupter (GFI) or Residual Current Device (RCD) is a device that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person. G    (2004 NFPA 70E) T    Extension cords may not be used as permanent wiring and should be removed after temporary use for an activity or event. UW personnel need to be aware of the hazards electricity poses, such as shock, fire and explosion, and either eliminate or control those hazards. 32 Part 2 Electrical safety duties We rely on electricity, but sometimes underestimate its capability of causing injury. Basic Electrical Safety. A    This fact sheet provides general guidance for persons conducting a business or undertaking (PCBUs) and workers on managing electrical risks at the workplace. This standard specifies those matters applicable to the machinery portion of the industry as included in the IEC 61508 Series Functional Safety Standards. I    Electrical shock happens when current passes through the body. J    No matter how much training one has received or how much employers try to safeguard their workers, Electrical Safety is ultimately the responsibil-ity of the electrical worker. The risk of injury changes according to the frequency of the AC, and it is common for DC to have an AC component (called ripple). If you are working at a power station or remote area to fix something at height, always perform a brief inspection of the area to look for possible threats and eliminate them before beginning work. Y    Grounding the electrical device gives electricity another path to pass through, so you don’t become part of the circuit if you accidentally come into contact with the electricity. 1 adj Electrical goods, equipment, or appliances work by means of electricity. Electrical grounding provides an alternate path for electricity to follow, rather than going through a person. Equipment with a grounding prong must be plugged into an extension cord with a ground; the grounding plug should not be removed from the equipment.Â. The basic means of protection is Test your devices regularly. For more information on electrical cords, including extension cords and power taps, see the Extension Cords, Surge Suppressors and Power Strips Focus Sheet. Electrical Safety Dedicated To Keeping You Safe With Electricity When working in the industrial field, knowledge on the operations of light to heavy machinery is often a requirement and with that lockout tagout procedures are a must. Never forget to ground the electrical device you are dealing with. To prevent any unwanted situations, take the most basic electrical safety measures recommended by the Occupational Safety and Health Administration (OSHA), which are listed below: Join thousands receiving the latest content and insights on health and safety industry. R    . Are there risks for healthcare workers who are on their feet all day? Reference. X    Please note that although HEI 95 and DB9801 are no longer current, they are referred to in the text since many medical electronics departments have used them as a basis for local acceptance testing and even routine testing … Â. Do not access, use or alter any building’s electrical service, including circuit breaker panels, unless you are specifically qualified and authorized to do so. If there is water on the floor, or your hands, feet, or other body parts are wet, never deal with electricity. Wet environments can increase the risk of an electrical shock. Electrical Safety -- Don't Be Shocked! D    For electrical safety in the workplace, OSHA relies on expert consensus bodies such as the National Fire Protection Association (NFPA) and its standards published in NFPA 70E. Ask a qualified person to perform these tasks. This can happen if someone touches both wires of an energized circuit, touches one wire of the circuit while standing unprotected or touches a metal part that has become energized. One challenge that's got many electricians, safety trainers, and frontline workers confused is the definition of low voltage. . Always refer to the safety precaution manual, and check for all the safety equipment before coming in contact with electrical wires or devices. Electrocution refers to the injury or lethal dose of electrical energy. 26-2 Construction Health and Safety Manual ELECTRICAL HAZARDS A major cause of accidents involving electricity comes from the failure to identify the hazards associated with live electrical equipment and wiring (Figure 26-1). In addition to gloves, your footwear must also be safe. Some of the serious injuries you can receive from electricity include electrical shocks, electrical burns, and electrocution, which could be fatal. Electrical safety is a general practice of workers who are exposed to handling and maintaining electrically powered equipment. 22 15 Duty to determine whether equipment is energised . Here's Why It Should Be, Hiring Contractors? F    The specific safety-related work practices shall be consistent with the nature and extent of the associated electrical hazards. Scope . Maintain at least 30 inches of clearance in front of electrical panels to ensure a safe environment for facilities workers. wet environment / presence of flammable vapors); and • Unsafe work performance Electricity travels through closed circuits, and people, sometimes tragically, can become part of the circuit. The GFCI ensures that any electrical shock is brief. - Renew or change your cookie consent, Meet the Author with Carsten Busch: Preventing Industrial Accidents, One Percent Safer Through Vision Zero and Marginal Gains, WIS #22: Human Capital & Sustainability: Influencing the Future of OHS, Electrolytes: What They Are and Why They Matter for On-the-Job Hydration, Safety Talks #18 - Heat Stress Preparedness, Work Locations and Vocations That Require Hydration Year-Round, Quiz: Test Your Knowledge About Heat and Hydration, 7 Lesser-Known Factors That Contribute to Heat Stress, Safety Benefits of Using Sound Masking in the Office, Protecting Your Hearing on the Job: The 5 Principles of Hearing Protection, Safety Talks #5 - Noise Exposure: Evolving Legislation and Recent Court Actions with Andrew McNeil, What Senior Management Needs to Know About Hearing Protection. Unable to adhere to electrical safety can lead to accidents, near misses, or even fatalities.
